Decimal Data Type

Decimal Data Type

You can use the Decimal data type to read and write data to flat files and supported databases, such as Oracle, Microsoft SQL Server, IBM DB2, and ODBC.
For transformations that support precision up to 38 digits, the precision is 1 to 38 digits, and the scale is 0 to 38.

Transformations that Support Decimal Data Type

The following transformations support the Decimal data type with precision up to 38 digits and can perform calculations on the data:
  • Aggregator
  • Data Masking
  • Expression
  • Filter
  • Java
  • Joiner
  • Lookup
  • Normalizer
  • Rank
  • Router
  • Sequence Generator
  • Sorter
  • Union
  • Update Strategy

Transformations with Pass-Through Support for Decimal Data Type

Some transformations can only pass decimal data with precision up to 38 digits through the transformation. The transformation cannot perform any calculations on the data. When you use a Decimal data type with precision up to 38 digits for performing calculations on the transformations, the Data Integration Service processes the data type as Double.
The following transformations have pass-through support for Decimal data type with precision up to 38 digits:
  • Data Processor
  • Hierarchical to Relational
  • REST Web Service Consumer Transformation
  • SQL
  • Web Services Consumer

Transformations that do not Support Decimal Data Type

Some transformations do not support Decimal data type, such as Data Quality transformations.
The following applicable list of Data Quality transformations do not support Decimal data type with precision up to 38 digits:
  • Address Validator
  • Association
  • Case Converter
  • Classifier
  • Comparison
  • Consolidation
  • Decision
  • Key Generator
  • Labeler
  • Match
  • Merge
  • Parser
  • Standardizer
  • Weighted Average
For transformations that do not support the Decimal 38 data type, when a Decimal data type has precision greater than 28 digits, the Data Integration Service converts decimal values to double in high precision mode.
